組み合わせた係合部によって行われる。To electrically connect the horn switch provided on the rotating steering wheel and the lever combination switch provided on the non-rotating steering column, use a relay means equipped with a spiral coil tape conductor, a brush and a slip ring. The relay means provided is used. The relay means is arranged around a cancel cam that rotates together with the steering wheel so as to surround the cancel cam, and the rotation of the cancel cam is transmitted via a rotating member. Transmission of the rotation to the rotation member is generally performed by a plurality of projections radially provided on one of the cancel cam and the rotation member and a plurality of projections formed on the other end surface corresponding to the projections. It is performed by the engaging portion in combination with the U groove.

れをなくすことを目的としてなされたものである。When the steering wheel is assembled to the steering shaft, tilting and eccentricity with respect to the steering column are unavoidable due to dimensional errors in parts and variations in work, and the gap between the protrusion and the U groove that accompanies rotation of the steering wheel is inevitable. Misalignment may cause squeak noise, and in an extreme case, it may be twisted and the engagement portion may be damaged.
If the clearance between the protrusion and the U groove is increased to avoid this, a collision noise is likely to occur at the time of cancellation. The present invention has been made in view of these problems, and has been made for the purpose of eliminating twisting of the engaging portion.

施してアール部を形成している。In order to achieve the above-mentioned object, in the rotation transmitting device for a steering wheel of the present invention, an engaging portion between the cancel cam and the rotating member is radially provided on one of the cancel cam and the rotating member. It is composed of a plurality of protrusions and a plurality of U grooves formed on the other end face corresponding to the protrusions, and both side surfaces of the protrusions are inclined so that the side facing the bottom of the U groove becomes thin. At the same time, chamfering is applied to both end edges of the U groove to form a rounded portion.

い。According to this invention, since the protrusion has a cross-sectional shape in which the side facing the bottom of the U groove is thin, the lower edge of the protrusion does not abut against the U groove strongly even if there is some inclination. Further, since the U groove is chamfered at both end edges to form a rounded portion, eccentricity does not cause twisting even if there is some deviation between the protruding direction of the protrusion and the U groove direction.

ある。Next, one embodiment shown in the drawings will be described. FIG. 1 is a sectional view of a relay means portion in a steering wheel, and FIG.
The figure is a bottom view thereof, FIG. 3 is a perspective view of a main part, FIG. 4 is a perspective view of a protrusion and a U groove, and FIGS. 5 (a) and 5 (b) are operation explanatory views. In the figure, 1 is a steering wheel, 2 is a relay unit, 3 is a rotating member which is also a movable side case of the relay unit 2,
Reference numeral 4 is a cancel cam for returning a turn signal switch (not shown) to the neutral position in response to the rotation of the steering wheel. Steering wheel 1 is a boss
The cancel cam 4 is fixed to a steering shaft (not shown) by 1a, and the cancel cam 4 is biased upward by a spring (not shown) so that the pin 5 at the upper end of the cancel cam 4 engages with the engaging hole of the boss portion 1a to rotate with the steering wheel 1. It has become.
The relay means 2 has a well-known structure in which a spiral coil tape conductor 2b is provided in the fixed case 2a, and a horn switch provided on the steering wheel 1 is electrically connected to the fixed steering column side. ing. 6 is a column cover. Reference numeral 11 denotes a projection radially provided on the inner side of the lower end of the rotating member 3 toward the axial center, and 12 denotes a U groove radially formed on the upper end surface of the cancel cam 4 corresponding to the projection 11. The combination of the protrusion 11 and the U groove 12 constitutes the engaging portion 13. Then, the projection 11 has an inclined surface 11a formed by inclining the lower halves of both end surfaces so that the side facing the bottom of the U groove 12, that is, the lower side in this embodiment, becomes thin. All rounded edges are chamfered to form the rounded portion 12a. Depending on the structure of this portion, the projection 11 may be provided on the cancel cam 4 and the U groove 12 may be provided on the rotating member 3 on the contrary. This embodiment has the above-described structure, and when the steering wheel 1 is rotated, the cancel cam 4 is also rotated, and this rotation is transmitted to the rotating member 3 by the engaging portion 13. Therefore, the rotating member 3 rotates to rotate the coil tape conductor.
2b is appropriately deformed following this, and the electrical connection is maintained regardless of the turning position of the steering wheel 1. Here, since both side surfaces of the projection 11 are inclined surfaces 11a, even if the inclination θ 1 occurs between the axes as shown in FIG. The lower edge of the side is U
The groove 12 is hard to hit, and the twisting with the U groove 12 does not occur. The U groove 12 has rounded edges 12 at both edges.
Since it is a, even if the inclination θ 2 with respect to the axis is generated in the direction of the protrusion 11 as shown in FIG. 5 (b), the side surface of the protrusion 11 contacts the U groove 12 by the radius portion 12a. It becomes difficult and the twisting with the U groove 12 does not occur. Therefore, even if an inclination or an eccentricity is generated between the rotating member 3 and the cancel cam 4 due to a dimensional error of parts, a variation in work, or the like, a squeak sound is generated or the engaging portion 13 is engaged.
It is possible to avoid the occurrence of twisting that may damage the.

る。As is apparent from the above-described embodiments, the present invention makes both side surfaces of the projection forming the engaging portion between the cancel cam and the rotating member inclined, and all the both end edges of the U groove with which the projection engages. The chamfer is formed on the to form the rounded portion. Therefore, even if tilt or eccentricity occurs between the rotating member and the cancel cam, twisting is less likely to occur, and it is possible to prevent generation of squeak noise and damage to the engaging portion with a simple configuration. Further, since it is not necessary to make a large clearance between the protrusion and the U groove in order to avoid the twisting, it is possible to prevent the operation feeling from being deteriorated due to the collision noise at the time of cancellation.
